Compression forces generated by Mini bone screws--a comparative study done on bone model.

The compressive forces generated by the AO/ASIF 3.0 mm cannulated cancellous and 2.0 mm cortical screws, Mini-Acutrak and Herbert/Whipple small bone cannulated screws were measured in the laboratory with the use of simulated cancellous bone and a load cell washer as a means of quantifying their fixation capabilities.

Upper-extremity deep-vein thrombosis following a clavicular fracture.

Upper-extremity deep-vein thrombosis (DVT) is not frequently reported in orthopaedic literature. We report a case of upper-limb DVT following an acute clavicular fracture that was treated conservatively with a figure-of-eight sling. Diagnosis of this condition requires a high index of suspicion, and treating it would prevent a potentially fatal pulmonary embolism.
